Dual 3" exhaust?

yevgenievich · Nov 20, 2021

Took my tahoe to exhaust shop again. Doubling up on mufflers. Will have two small body mufflers( jfp300) followed by large turbo style mufflers(quiet-flow 54637) then resonators. Mufflers that exhaust shop used to make it less noisy ended up being louder than magnoflows I had on it before. This will be 4th muffler iteration with this engine.
